| Abstract |
| The magnesites from different sources in! India indicate a wide variation in their
chemica,z composition namely Si02 from 0.6 to 8.0, MgO 36.4 to 46.7, CaO 0.1 to
9.7 and Fe20 3 0.2 to 4.4 per cents. Si02 is derived essentially from quartz in case
of magnesites from Salem, Mysore and Rajasthan, and from talc in the Almora
magnesites. CaO is constituted usually from dolomite calculated to be present in
proportion varying from about 0.5 to 30.8 per cent. The determination of magnetic
susceptibility on powder-compacts of natural magnesite as per Guoy method
suggests the Almora magnesites to be simi/c.tr to breunnerite of Austria containing
siderite in variable proportion in solid solution in magnesite. |
